Small Business Website Accessibility Basics

Website accessibility means people with disabilities can use your site: read it with a screen reader, move through it with a keyboard, see the text, hear or read the video, and fill out your forms. It is a good practice and a legal concern, and most of the fixes are ordinary design and content work. The practical target is WCAG 2.2 level AA, and the quickest way to improve is to fix the handful of mistakes that appear on most sites. A widget that you add to your site does not do that work for you.

This is general information, not legal advice. Whether a particular law applies to your business is a question for your attorney.

What WCAG is, in plain English

The Web Content Accessibility Guidelines (WCAG) are the international standard for web accessibility, published by the W3C. They organize requirements around four ideas: people must be able to perceive your content, operate the interface, understand it, and rely on it across different tools. Each requirement has a level: A, AA or AAA. AA is the level most laws, contracts and policies refer to.

WCAG 2.2 adds nine criteria to 2.1 and removes one obsolete one (4.1.1 Parsing). The new AA items matter for small sites: a focused element must not be hidden behind sticky headers or banners, anything that works by dragging must have a click alternative, pointer targets should be at least 24 by 24 CSS pixels (or have enough spacing), and login steps should not require a memory test.

Is your business legally required?

It depends, and we are not lawyers. What the public sources say:

• The Department of Justice states that the ADA applies to the goods and services of businesses open to the public, including online. It also says it has no regulation setting detailed technical standards for these businesses, and points to WCAG and Section 508 as helpful guidance.
• State and local governments have a specific DOJ rule published in 2024. Healthcare providers that receive HHS funding have their own rule under Section 504, with compliance dates currently in 2027 and 2028 according to reporting on HHS's May 2026 interim rule. Check the current dates with your counsel.
• Government contracts and corporate customers often require WCAG AA in writing.

For most small businesses, the sensible reading is: accessibility is expected, WCAG 2.2 AA is the benchmark everyone uses, and a good-faith, documented effort protects both your customers and you.

What goes wrong most often

WebAIM's 2026 analysis of the home pages of the top one million websites found these failures most common, as a share of pages:

Those six categories accounted for 96% of the detected errors. That is encouraging, because they are fixable by anyone who edits your site.

Quick wins you can do this week

1. 1Contrast. Body text needs a contrast ratio of at least 4.5 to 1 against its background, and large text at least 3 to 1 under WCAG AA. Light gray on white and white text over photos are the usual failures. A free contrast checker will tell you.
2. 2Alternative text. Every meaningful image gets a short description of what it shows or does. Decorative images get empty alt text. "Image of a plumber" is not useful; "Technician replacing a water heater in a garage" is.
3. 3Form labels. Every field has a visible label tied to it, not just placeholder text that disappears. Error messages say what to fix.
4. 4Link and button names. "Click here" and "Read more" mean nothing out of context. Icon buttons need a text name.
5. 5Headings in order. One main heading, with subheadings in logical order, because screen reader users move through a page by heading.
6. 6Keyboard use. Press Tab on your site. Can you reach every link, menu and button, in a sensible order, and see where you are? Can you open and close menus and popups without a mouse?
7. 7Captions and transcripts. Spoken video needs captions. Audio needs a transcript.
8. 8Text size and zoom. The page should still work when zoomed to 200 percent and on a phone.
9. 9No autoplay or flashing. Offer controls for moving content.
10. 10Declare the page language in the page code. Your developer can do it in minutes.

How to test in an afternoon

1. 1Run an automated checker. Browser tools and free scanners find a portion of the problems, not all of them, because they cannot judge whether alt text is meaningful or whether a flow makes sense.
2. 2Unplug the mouse and use only the keyboard to complete your most important task, such as booking or checking out.
3. 3Zoom the page to 200 percent and view it on a phone.
4. 4Turn on a screen reader (VoiceOver on Mac and iPhone, Narrator on Windows, TalkBack on Android) and listen to your home page and contact form.
5. 5Write down what you find, fix the highest-impact items, and date your notes.

What an accessibility overlay does not fix

Overlay widgets are scripts that add a toolbar or claim to repair your site automatically. Automated tools generally cannot write meaningful alt text for your photos, caption your videos accurately, fix a layout that traps keyboard users, or relabel a form built wrongly underneath. The FTC took action over exactly this kind of claim: in 2025 it finalized an order requiring accessiBe to pay $1 million and barring it from representing that its automated products can make any website WCAG-compliant without evidence. That is one company's order, not a ruling on every product, but it is a clear signal to be skeptical of any promise of instant compliance. Fixing the site itself is what works.

If an overlay is already on your site, do not rely on it. Fix the underlying issues and check with your counsel before you remove it.

Make it part of how you build

It is cheaper to build accessibly than to repair later. Ask any designer or agency about contrast, keyboard use, labels and captions at the start of a project, and ask how they test. Our website checklist before you hire is a good list to bring. For restaurants, clinics and firms, accessibility ties into the rest of the site too: see medical practice website basics and law firm website essentials.

Want a person to look at it?

We build with accessibility in the plan from day one, and we can review an existing site against these basics. Start with the website check, or start a quote and ask for an accessibility review as part of the work.
